Timestamp Helper

Quickly copy the current timestamp or convert between timestamps and readable time, supporting multiple time zones.

Timestamp Helper lets you copy the current timestamp with one click, convert between Unix timestamps and readable date-time formats, and compare results across multiple time zones. It now supports both fixed UTC offsets and IANA city time zones (with searchable city/zone picker), so daylight saving time (DST) is handled automatically for regions like the US and Europe. The extension includes expanded multilingual UI support (including English, Simplified Chinese, Japanese, Korean, Spanish, German, French, Portuguese, Russian, Italian, and Dutch), while remaining lightweight and easy to use. All calculations run locally with no network dependency, giving you faster workflow and better privacy for development debugging, API testing, and log analysis. Install it once, open the popup anytime, and eliminate repetitive time conversion work.
